Tam sim no muaj ob lub ntsiab ntawm cov yas degradable. Ib tug yog kiag li decomposed rau hauv dej thiab carbon dioxide. Cov khoom siv feem ntau yog PBAT thiab PLA, Biodegradable cov hnab khib nyiab uas tau ntim nrog cov hmoov txhuv nplej siab rau polymerize rau hauv cov ntaub ntawv degradable. Lawv tau ua rau ntau hom hnab los ntawm tshuab tshuab luam ntawv. Cov hnab ntim khoom, suav nrog cov hnab ntim khoom, Biodegradable garbage hnab khib nyiab, zaj duab xis thiab lwm yam khoom.
Qhov tsis zoo ntawm cov khoom siv no yog tias nws lub zog tsis zoo li HDPE zoo tib yam, nws lub cev muaj zog tsis zoo rau HDPE hauv ntau yam, Biodegradable hnab khib nyiab thiab nws cov nqi siab. Nws yog ib qho nyuaj rau rov ua dua cov khoom seem hauv kev tsim khoom, ua rau cov nqi tsim khoom yog li peb npaug ntawm HDPE zoo tib yam (high-density polyethylene) hnab. Biodegradable garbage bags Tshwj xeeb tshaj yog cov hnab khib nyiab, feem ntau cov hnab khib nyiab yog tsim los ntawm cov khoom siv rov ua dua tshiab.
Yog tias lawv tau ua rau hauv cov khoom siv degradable, Biodegradable cov hnab khib nyiab tus nqi yuav ncav cuag li tsib zaug, thiab nws qhov tshwj xeeb lub ntiajteb txawj nqus, tib lub thickness ntawm lub hnab, Biodegradable khib nyiab hnab nws qhov hnyav yog 30 hnyav dua li HDPE %, nws yog ib qho nyuaj rau kev lag luam dav dav thiab cov tib neeg los txais.
